Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get your bids” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "tendsign.com/get_bids",
    "input": {}
  }'

{
  "status": "completed",
  "data": {
    "bids": [
      {
        "bid_name": "Acme anbud ramavtal IT-konsulter",
        "procurement": "Ramavtal IT-konsulttjänster 2027",
        "contracting_authority": "Northwind kommun",
        "case_officer": "Bid team",
        "status": "Påbörjat",
        "tender_deadline": "2026-11-27"
      }
    ],
    "count": 1
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

TendSign’s own options

Mercell's supplier pages and the TendSign knowledge base describe no API, export or file exchange for suppliers. The supplier account is free, and bids, tender documents and questions are handled in it on the web. Bevakning emails you when a tender you follow changes, and Mercell offers Opic as a separate product for finding tenders and ordering competitors' bids.

Signing in to TendSign

TendSign signs you in with a username and password on tendsign.com, and the username can differ from your email address if you have several accounts. Signing a contract is a separate step, through a link the buyer emails, confirmed with BankID or e-legitimation. With Fous you sign in once through TendSign's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

The Anbud page follows your rights

Min startsida shows only your five most recent bids under Senast använda anbud. The Anbud page lists all of yours, plus the organisation's bids you have read or write rights to.

Who can sign a bid

Bids are signed by a firmatecknare (authorised signatory), or by someone with a power of attorney registered with ChamberSign. Contracts are signed through a link the buyer emails, confirmed with e-legitimation or BankID.

Award decisions arrive by email

The buyer emails the tilldelningsbeslut to every supplier that bid. It can also be found in the bid process under the tab Besluta, Ta del av beslut.

Over 10 wrong passwords block the account

After more than 10 failed sign-ins the account is blocked, and Forgot password no longer works. Mercell's support has to restore it.
